BOTTLE AND STOPPER THEREFOR.

SPECIFICATION forming part of Letters Patent No. 452,810, dated May 26, 1891. Application filed February Z6, 1891. Serial No. 383,009. (No model.)

T0 @ZZ whom, it may concern:

Be it known that I, FRANK C. II. STRAS- BURGER, residing' at Chicago, in the county of Cook and State of Illinois, and a citizen of the United States, have invented a new and useful Improvement in Bottles andStoppers, of which the following' is a specification.

The object of my invention is to provide a stopper which shall be tight whether the contained liquid be under a pressure or not, and which shall be so connected with the bottle as to be easily opened without special appliances to allow the contents of the bottle to be removed, but which shall not be entirely detachable from the bottle, except by means of special devices.

Another purpose of my invention is to make the bottle and stopper so that when the bottle has once been opened it cannot be closed without special appliances, the result of the last-named feature being to prevent theirbeing put to any use except that for which they were specially designed. Such Stoppers are particularly adapted for use by bottlers, as they insure certain and speedy return of the bottles without their diversion to other uses.

In the drawings, Figure l is a vertical section of the stopper and the neck of the bottle on which it is applied. Fig'. 2 is a similar vertical section upon a plane at right angles to that of Fig. l. Fig. 3 is a horizontal sec* tion on line 3 3 of Fig. l. Fig. 4 shows the manner of replacing the stopper. Fig. 5 is a face view of the replacing-tool shown in Fig. 4.

The stopper consists of a disk A, of com! pressible material, upon the top of which is a cap B, of rigid material, preferably a thin metal plate. Passing through the parts A and B is a link C, firmly fastened by soldering or otherwise to the cap I3. A ring D is passed through the upper end of the link C, and from the lower end of the link C, which projects below the disk A, is hung a forked spring E, the middle portion of which is preferably formed into a coil of one or more turns, as shown in the lign res, said coils passing through the link C. The lower ends e c of the spring are bent outward, so as to en gage beneath an internally-projecting rib F F, formed within the neck of the bottle. The lower face of the rib F F projects inward perpendicular to the axis of the bottle-neck, so as to form a shoulder, which affords a secure hold for the bent ends of the spring E, and the upper face of the rib is made inclined,so as to compress the spring E as the stopper is forced downward.

Above the rib F F is formed an annular groove G, whose sides are perpendicular, or practically so, to the axis of the bottle-neck, a'nd into this groove the outwardly-bent ends e e spring' when the stopper is raised. In oi'- der to permitthe stopper to be raised, grooves ff are formed through the rib F F, so that by partially revolving the stopper and its attached spring the endse c of the latter are brought opposite the grooves ff. IVhen the Stopper has been withdrawn suiiiciently to allow the ends c c Vto spring into the groove G, it is thereby locked in position, as the perpendicular sides of the groove form retaining-shoulders both above and below the ends e e, and the spring E is made sulciently stiff to prevent its compression, except .by niechanical means, as shown in Fig. a. It is thus impracticable for unauthorized persons to make any further use of the bottle.

The use of a forked spring hung loosely from an eye or lilik secured to the stopper is of advantage in that it permits the stopper to bear evenly upon the mouth of the bottle, and it also permits the use of a coil in the spring, which gives the latter sufficient elasticity to insure its durability and efficiency. It likewise ena-bles the stopper to be conveniently replaced by the pliers Il., as shown in Figs. et and 5.

IVhat I claim as new, and desire to secure by Lett-ers Patent, is as follows:

l. The combination, with a bottle havinga retaining-shoulder within its neck, of a bottie-stopper comprising a compressible disk capped by a rigid disk, and a forked spring connected to said disks, having outwardly-bent ends, said retaining-shoulder being so situated within the bottle-neck as to to permit said outwardly-bent ends to engage therewith only when the stopper is closed, substantially as described.

2. The combination, with a bottle having upper and lower retaining-shoulders within its neck, the rib which forms the lower shoulder having grooves formed through it, of a ICO stopper having a forked spring depending therefrom, said spring having outwardly-bent ends adapted to engage one of said shoulders when the stopper is open and the otheuwheu the stopper is closed, substantially as described.

3.,The combination, with a bottle having upper and lower retaining-shoulders Within its neck, the rib which forms the lower shou1 del1 having grooves formed through it, the upper of said shoulders being formed by an annular groove having perpendicular sides, of a stopper having aforked sp1-ing depending therefrom, Sad spring having' outwardlybent ends adapted to engage one of said shoulders when the stopper is open :md the other when the stopper is closed, substantially as described. u
